The hex color #021E66, a deep sapphire, presents significant accessibility challenges, especially in web design. Its extremely low luminance value (very dark) means that text or interactive elements using this color as a background require very light foreground colors to ensure sufficient contrast. A contrast ratio of at least 4.5:1 is recommended for standard-sized text and 3:1 for large text, as per WCAG guidelines. Without adequate contrast, users with visual impairments, including those with low vision or color blindness, will struggle to read content or interact with the interface. Designers should carefully test color combinations using contrast checkers and consider providing alternative color schemes to meet diverse user needs. Furthermore, avoid using this color alone to convey important information, as colorblind users may not perceive it. Supplement color cues with text labels or other visual indicators to enhance accessibility.
